Chained method calls

Reports method calls whose target is another method call. The quick-fix suggests to introduce a local variable.

Example:

  class X {
    int foo(File f) {
      return f.getName().length();
    }
  }

After the quick-fix is applied:

  class X {
    int foo(File f) {
      final String name = f.getName();
      return name.length();
    }
  }

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

ChainedMethodCall

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Code style issues

Use the inspection options to toggle warnings for the following cases:

chained method calls in field initializers, for instance, private final int i = new Random().nextInt();
chained method calls operating on the same type, for instance, new StringBuilder().append("x: ").append(new X()).append("y: ").append(new Y()).toString();.

Here you can find the description of settings available for the Chained method calls inspection, and the reference of their default values.

Ignore chained method calls in field initializers: Default: Selected
Ignore calls to methods returning the same type as their enclosing class: Default: Selected
